A RENOLIT ALKORGREEN roof system serves as an excellent sound insulator. Green roofs can be very efficient in reducing indoor noise attenuation from hail and rainfall etc…

Green roofs contribute to an improved air quality, especially in urban environments where the quality of the air is often unsatisfactory. The vegetation on the rooftop produces oxygen on the one hand and absorbs polluted particles from the air on the other hand.

Green roofs create more natural green areas in the urban environment. The plants on the roof give the owners a more natural view, instead of the increasingly dominating black or grey flat roof surfaces.
